Pull-out guide for drawers

ABSTRACT

A pull-out guide for drawers ( 2, 3, 4 ) having on the two sides of the drawer ( 2, 3, 4 ) in each case a support rail on the carcass side and a pull-out rail ( 6 ) on the drawer side. The pull-out rails ( 6 ) are provided at their rear ends with hooks ( 8 ) which have horizontal holding lugs ( 10 ) which in the mounted position project into openings ( 9 ) in the drawer ( 2, 3, 4 ). The position of the holding lugs ( 10 ) or the hooks ( 8 ) with the holding lugs ( 10 ) on the pull-out rails ( 6 ) is adjustable in the vertical direction.

DESCRIPTION

[0001] The invention relates to a pull-out guide for drawers having on the two sides of the drawer in each case a support rail on the carcass side and a pull-out rail on the drawer side, the pull-out rails being provided at their rear ends with hooks which have horizontal holding lugs which in the mounted position project into openings in the drawer, preferably in the drawer frames.

[0002] The invention further relates to a drawer having a pull-out guide of this type.

[0003] The conventional adjustment devices for wooden drawers (adjustment of inclination and height) are usually placed in the vicinity of the front panel of the drawer for the sake of good accessibility.

[0004] The disadvantage of this arrangement consists in the fact that neither the height of the front panel nor the inclination of the front panel can be adjusted independently of one another, but rather that adjustment always takes place in both dimensions at the same time, although in most cases this is not desired.

[0005] Furthermore, pull-out guide fittings are known in which the pull-out rails on the drawer side have at their rear ends hooks which project into bores in the drawer. The pull-out rails are thus anchored in the drawer at the rear end.

[0006] The object of the invention is to provide an improved adjustment device by means of which it is possible to adjust only the inclination of the panel, with the height position of the panel being practically retained.

[0007] The object according to the invention is achieved in that the position of the holding lugs or the hooks with the holding lugs on the pull-out rails is adjustable in the vertical direction.

[0008] The drawer according to the invention is characterised in that the holding lugs or the hooks with the holding lugs may be moved in the vertical direction on the pull-out rails, with the drawer bearing on the pull-out rails in the front region, also height-adjustably, by means of wedges.

[0009] If the height of the front panel is adjusted by displacing the wedges, the inclination of the panel which is thereby caused can be corrected by adjusting the hooks or holding lugs. In this way, the correct profile for a join or for a panel in an item of furniture may be achieved.

[0010] A preferred example embodiment of the invention provides for the hooks or the holding lugs to be adjustable by means of a handle, without a tool.

[0011] Two example embodiments of the invention will be described below with reference to the figures of the accompanying drawing.

[0012]FIG. 1 shows diagrammatically an illustration of an item of furniture with drawers,

[0013]FIG. 2 shows a vertical section through an item of furniture with drawers,

[0014]FIG. 3 shows diagrammatically and in exploded view the rear adjustment device,

[0015]FIG. 4 shows a vertical section through the rear adjustment device on the rail side,

[0016]FIG. 5 shows an exploded illustration of the rear end of a pull-out rail and a further example embodiment of the adjustment device,

[0017]FIG. 6 shows an illustration of this example embodiment, with the adjustment device shown in the topmost position,

[0018]FIG. 7 shows an illustration of this adjustment device, with the adjustment device shown in the bottommost position,

[0019]FIG. 8 shows a longitudinal section through the rear end of a pull-out rail and the adjustment device, and

[0020]FIG. 9 shows an end view of this example embodiment of the adjustment device and the pull-out rail as seen from the rear.

[0021] Drawers 2, 3, 4 are arranged one above the other in a furniture carcass 1. The drawer 2 is in this case located in the centre position, with its front panel 5 aligned straight, while in the case of the drawer 3 the front panel 5 is inclined forwards and in the case of the drawer 4 it is inclined towards the rear. The drawers 2, 3, 4 are anchored on pull-out rails 6 which each form part of a pull-out guide fitting.

[0022] Here, the drawers 2, 3, 4 bear on the pull-out rails 6 in the front region by means of displaceable wedges 7.

[0023] In the rear region of the drawers 2, 3, 4, an opening 9 is provided in each drawer frame in the form of a receiving bore for a holding lug 10 of a hook 8.

[0024] In the example embodiment according to FIGS. 2 to 4, the hook 8 is secured to a stirrup-shaped piece 14 of the pull-out rail 6 by means of a screw 11, and is adjustable vertically with respect to the pull-out rail 6. In this connection, the screw 11 is connected form-fittingly to the hook 8 and engages in a thread in the stirrup-shaped piece 14. The stirrup-shaped piece 14 may be punched out of the pull-out rail 6 or be connected to the latter by welding or the like.

[0025] The pull-out rail 6 is furthermore provided in the rear region with a recess 13. A bearing tab 12 constructed on the hook 8 projects into this recess 13 and in the mounted position the drawer frame or the drawer base lies on the bearing tab 12. The drawer 2, 3, 4 is thus held between the holding lug 10 of the hook 8 and the bearing tabs 12.

[0026] By turning the screw 11, the inclination with respect to the drawer 2, 3, 4 and thus the front panel 5 may be adjusted without any adjustment of the height of the front panel 5 taking place at the same time.

[0027] In the example embodiment according to FIGS. 5 to 9, the hook 8 and thus the lug 10 are adjustable by means of a handle 15, without a tool.

[0028] The hook 8 is guided in a support 17. The support is constructed to be U-shaped as seen in plan view, and is preferably made from a steel sheet which is connected to the pull-out rail 6, for example welded thereto.

[0029] The support 17 has a recess in the form of a horizontal elongate hole 18.

[0030] Provided on the handle 15 is an eccentric 16 which in the mounted position is received in the elongate hole 18. A peg 19 which projects into a hole 20 in the hook 8 is constructed on the eccentric 16.

[0031]FIGS. 6 and 7 shows the two limit positions of possible adjustment of the hook 8 and the lug 10. In both limit positions, the handle 15 is in each case located on the side of the support 17 and the hook 8.

[0032] Height adjustment of the drawer is performed by pivoting the handle 15.

[0033] The hook 8 is, in this example embodiment, provided with two bearing webs 12 which are received in slot-shaped recesses 13 in the pull-out rail 6.

[0034] A washer 21 is placed on the peg. The peg 19 is riveted.

[0035] Once the position of the front panel 5 has been adjusted with respect to height by displacing the wedges 7, undesired inclination of the front panel 6 may be compensated by adjusting the hooks 8.

[0036] Only so-called simple pull-out devices have been described. The adjustment device according to the invention could however be used with complete sets of pull-out devices, including pull-out rails, centre rails and support rails.
